To use these cat toys, simply give them to your cat and watch as they start playing. You can also wave the toys around to stimulate your cat's hunting instincts. When it comes to maintenance, you can use a damp cloth to wipe the toys clean if they get dirty. Make sure to keep these toys away from other pets that might damage them. Also, if your cat loses interest after a while, you can try hiding the toys around the house to make it a fun hunting game. And always check the toys regularly for any signs of wear and tear to ensure your cat's safety.
